LaBeouf, 24, wore a suit on the red carpet, but all eyes were on the bag, which read: "I Am Not Famous Anymore" in black sharpie marker. (This is a comment he's been writing via Twitter almost every day since Jan. 13. Shortly after the premiere, he wrote it again.)

LaBeouf's antics in Berlin kicked off earlier in the day during a press conference for the film -- walking off after answering just one question. When asked why he joined a project with so many sex scenes, he replied: "When the seagulls follow the trawler, it is because they think sardines will be thrown into the sea." This quote can be attributed to former Manchester United football player Eric Cantona, who spoke the words following his conviction for assault at a news conference in 1995.

Last month, it was revealed that the actor plagiarized parts of his short film HowardCantour.com from David Clowes' 2007 novel Justin M. Damiano. After using skywriters to send an apology to Clowes, he announced via Twitter that he would be retiring from the industry.

"In light of the recent attacks against my artistic integrity, I am retiring from all public life," the former Transformers star tweeted on Jan. 10. "My love goes out to those who have supported me. #stopcreating."
